The Schedule referred to in these Letters4 Patent and making part oi' the same.

Beit known that I, N. L. SMITH, of Derby, in `the countyof New Haven, and State of Connecticut, have' invented a new and improved Water-Regulator and Alarm-Attachment toSteam-Boilers; and I do hereby' declare thatJ thefollowing is-a full, clear, and exact description thereof, which will enable those skilled in the art to make and use .the sameyreference being had to the accompanying drawings, forming` part of this specification, in which- Figure 1 represents a side elevation, partly in sec` Figure 2 is a plan or top view of the same.

' vessel, which is, by jointed or fiexible pipes, connected with the boiler, but not arranged within the same, and

which, vwhen it is filled with water, overcomes the power of aspring or weighted lever, and descends, op-Y erating', by that motion, either a valve to the pump,

or whistle, ora lever for throwing thepurnping-engine ,out of gear, Whileit-willbe raised to` set the pumpcr alarm in motion when too little water should be in it. 'A, in the drawing, representsa frame, 'of suitablesize and'form, in which a hollow vessel,-B, ofsuitable size, is-held.

This vesselrests only on aspring, C, or on a weighted lever, `whereby it is held raised, if Atoo light.

By means of twojointedorflexible pipes, Dand E,

the vessel B is connectedwithfthe steamfboiler E., so

gure 3 is a side elevation of a modification of the that the Ywater shall be at yequal height vin both these vessels, B and F.

W hen the water in the boiler' should rise above la the boiler, or cause the blowing cfa whistle, `or both, so that thei'urtherrise of water in the boiler is either' automatically stopped, or notice `is given tostop it.

As soon as the water sinks in the boiler, the vessel 'B will get lighter, and will be raised by the spring or weighted lever, so as to open the valve a, to let in more water, or to sound au alarm.'

Instead ofthe `aforesaid apparatus and valve, the

vessel B may, as in fig. 3, act on a bellcra'nk, H,wl1ich is, by a rod, I, connected with the rod J, which serves to connect the pump-piston with the walking-beam K.

As soonas the vessel B descends, it will cause the r crank El to swing, whereby the rod J is swung off its connection with the beam, as indicated in iig. 3.- The rising of the vessel will automaticallyre-establish that connection. v

` I claim as new, and desire to secure by Letters Vatent- The arrangement of the yielding vessel B, stand A, and jontedpipes D E, with reference to theboilerF and'whstle G, when constructed substantially as herein set forth.
